reflection boundary condition
I am planning on using finite difference coding to solve a wave equation. The domain is a rectangular domian with wave reflection on the boundaries. Does anyone know how to set the reflection boundary condition?

Noncovalent bonds dictate cell rheology
Over the last ten years, a peculiar behavior of living cells is revealed: their modulus increases weakly with loading frequency (the so-called weak power law behavior) (for a pure elastic solid, the slope is 0; for a viscous fluid, the slope is 1). The underlying mechanism is not clear at all; although a phenomenological soft glass rheology model (a model based on a disordered structure system) has been proposed, it cannot explain the multi-power laws at different loading frequencies (see Stamenovic et al, Biophys J Letter, 2007).
Runing of input file
Dear friends,
if i have one input file i will import by file---model---inputfile
the i will see what they did in othermodules, for learning from exapmle problem
but if i have morethan one input file mean main input file and node information and element information both are seaprate input for reduc thesize of file.
how to import via part--model--
so how to merge this more than one input file
thanks and regards

Reg-element deletion
Dear Friends.
i am working on machining simulation.
when the element reaches the ultimate stress it should remove(chip flow) from part.
i used in input file
*shear failiure,type=johnson cook,Element deletion=yes
but still the removal is not good
so what can i do.
and if need to erite usersubroutine in VUMAT
please give me some information about that
if any body having usersoubroutin for element deletion case pease send me
please please

problem in modeling a concrete
HI, I have a problème in modeling a refractory concrete, How can I draw a simple of a concrete
shoremeter
hello everybody.
ı am looking for relationship between shore D and shore A.Not a curve i need chart.I would be appreciated if you send me this diagram.I have some hypolon and PU roll .I am using shoremeter to see the hardness .
if you have you may send violetlover [at] mynet.com (violetlover[at]mynet[dot]com)
have a nice day

Equilibrium and stability of dielectric elastomer membranes undergoing inhomogeneous deformation
Dielectric elastomers are capable of large deformation subject to an electric voltage, and are promising for uses as actuators, sensors and generators. Because of large deformation, nonlinear equations of state, and diverse modes of failure, modeling the process of electromechanical transduction has been challenging. This paper studies a membrane of a dielectric elastomer deformed into an out-of-plane, axisymmetric shape, a configuration used in a family of commercial devices known as the Universal Muscle Actuators.
Recommending a book on FSI with recent discussion on Immersed Boundary/Continuum Methods
I am writing to recommend my book “Fundamentals of Fluid-Solid Interactions-Analytical and Computational Approaches” recently published by Elsevier Science. The book is available in amazon.com webpage or Elsevier Science webpage. The following is
Tom Milnes' First Blog Entry
Hi All,
--I have taken 3 previous courses in solid mechanics.
--My undergraduate major was mechanical engineering, with a concentration in vehicle dynamics.
-- My strength is that I've had some of this material before. My weakness is that I haven't seen it for a few years.
--I'm a masters student so I don't have a research group. I do work part time for a hedge fund though.
--Solid mechanics will add an interesting dimension to my education.

contact & Geometric non linearity
I am looking for acadmic material to address contact & Geometric (Large deformation) non-linearity problem. Can anyone provide the material to address these two concept in details.
Thanks
